副室付２サイクルデイーゼル機関において、排気
弁側の給気弁周辺部に排気弁側の給気弁開口から
の新気の流入を抑制する新気流入抑制壁を設け、
該新気流入抑制壁を給気弁と排気弁を含む垂直平
面に対し給気弁の周辺方向にずらして形成すると
共に該垂直平面に関し新気流入抑制壁のずれ方向
と反対方向のシリンダヘツド内壁面周辺部に副室
の噴口を配置した２サイクルデイーゼル機関。 In a two-stroke diesel engine with an auxiliary chamber that has an intake valve and an exhaust valve in the cylinder head, fresh air is prevented from flowing into the area around the intake valve on the exhaust valve side from the intake valve opening on the exhaust valve side. Install an inflow control wall,
The fresh air inflow suppressing wall is formed by being shifted toward the periphery of the air intake valve with respect to a vertical plane including the intake valve and the exhaust valve, and the inside of the cylinder head is formed in a direction opposite to the shift direction of the fresh air inflow suppressing wall with respect to the vertical plane. A 2-cycle diesel engine with the subchamber nozzle located around the wall.
